PRINTING-STAMP.

SPECIFICATION forming part of Letters Patent No. 766,853,` dated August9, 1904.

i Application filed August 12, 1899.

To a/ZZ whom ima/y concern:

Be it known that I, LIBANUs M. TODD, of Rochester, in the county ofMonroe and State of New York, have invented certain new and. usefulImprovements in Printing-Stamps; and I do hereby declare the followingto be a full,

clear, and exact descriptionof the same,- reference beingA had to theaccompanying drawings, forming a part of this specification, and to thereference-numerals marked thereon.

My invention has for its object to provide an improved .printingapparatus or stamp particularly adapted for marking or embossing uponchecks, drafts, and similar instruments words or figures indicating alimiting amount beyond which such instrument is not good; and itconsists in certain 'improvements,'here inafter fully described, wherebynot only is the construction of the device simplified, but theoperations necessary to effect the marking ofv the check may be readilyaccomplished and the marking surfaces or forms'readily changedto bringone or the other of the series contained on` the printing-wheel inposition for printing, all as will be hereinafter described, and lthenovel features pointed out in the claims at the end of thisspecification.

In the drawings, Figure 1 is a side elevation Of a printing-stampconstructed in accordance with my invention; Fig. 2, a sectional viewtaken on the line mw of Fig. 3; Fig. 3', a longitudinal sectional viewtaken on the line y y of Fig. 4.; Fig. 4, a bottom plan view with thebottom of the casing removed.

Similar reference-numerals indicate similar parts.

The maincasing 1 of the machine is preferably composed of a singlecasting having the forward rounding portion for containing theprinting-wheel and open at the bottom, said opening adapted to be closedor partially closed by a base piece or block 2 of wood or other- J ustbeneath the .rounding portion of the casing is formed aslot or passage3, preferably formed by sawing through the casing ,and adapted for theentrance of a check,

draft,`or other instrument in position to be printed upon. J ournaled inthe casing is an .arbor or shaft 4,upon which is mounted a Serial No.727,052. (No model.)

printing-wheel 5, preferably secured in posit1on bya screw 6 and havingat lts periphery a series of notches or recesses in which are secured aseries of printing-forms 7, composed of a stereotype-block or line ofprinting-type 9, by means of which the printing-wheel may be rotatedtobring any of the numbers upon the dial 8 into cooperative relation witha suitable index 10 on the main frame. -The coincidence of thefigureswith the index indicates lthat the printing-form corresponding to thegures is on the under side in proper printing position. Thisprinting-wheel is freely rotatable and is centeredor yieldinglyl held inproper position with the printing-form directly above the cooperatingplaten, presently described,

by means of. a suitable centering device, in the i present instanceconsisting of a felt-covered rollel` 11, mounted upon an arbor 12,supported upon and pressed toward the center of the printing-wheel byspring-arms 13, as shown particularly in Fig. 3, the typefor'ms or-blocks constituting the necessary projections on the wheel or carrier.This felt-covered roller contains ink upon its surface and not onlyserves to center the printing-wheel by the `movement toward the arbor 4and between,

`the printing-forms 7, as described, but also "serves to'apply ink tothe surfaces of the type during the rotationV of the wheel in either di-"rection.

Located in the base of the main frame is a movable platen 16, preferablyprovided in its upper surface with a rubber, leather, or other suitableyielding block 17 and secured to `or l formed with arms 18, fittinginsockets se'- cured to or sleeved upon an oscillatory arbor 19, mountedin the frame, as shownin Figs. 3 and 4. This platen 16 is normally inadepressed position, as shown infull line'siiny Fig. 3, with the pad 17directly beneath'rthe center of the printing-wheel, so that a check orother instrument maybe introduced between the platen and printing-wheel,and the former may be moved up to press the paper into contact with thetype-form, the yielding pad in the platen serving to make a goodimpression and depending upon the force exercised, causing the type-formto more or less emboss or indent the paper, so that as the fibers arestretched the ink may sink into the paper` and prevent ready erasure. Inthe present embodiment the means for elevating the platen consists of alever 21, formed as Shown particularly in Fig. 4, pivoted upon an arboror shaft 22, secured in the sides of the main frame by a screw 2O orotherwise, and having on its shorter end or ends lugs. or abutmentsadapted when the rear end of the lever is pressed down to engage withthe under side of the platen 16 or, preferably, small inclined surfaces23 thereon to raise said Aplaten and bring the paper into contact withthe'printing-form. In the present embodiment the lugs are inthe form ofadjustable screws 211, so as to permit the greater or lesser elevationof the platen, as may be desirable or necessary, and the surfaces 23 onthe under side of the platen consist of hard-metal balls 14, arranged insockets formed in the latter and held in place by compressing orupsetting' the metal of the platenbeneath them to prevent theiraccidental removal, but without preventing their free rotation in thesockets, thereby reducing the friction between 4the parts, or,ifdesired, the balls may be made stationary, simply affording hardsmooth surfaces in which point contact only is had. The rear end of thelever 21 is slotted both vertically and horizontally, as shown, and inthe horizontal slots 25 is arranged a pin 26 on a plunger 27, verticallymovable through a suitable adjustable sleeve or collar 16 on the casingand also through a lug 2() formed in the latter. The upper end of theplunger is provided with a slot 30, in which operates a pin 31 on alever or handle 32, pivoted at 33 to a bracket 34 on the casing andhaving the broad forward end 35. The handle is held in raised positionby a spring, such as 36, whereby the platen is allowed 'to fall to itslowest position, as in full lines in Fig. 3. Interposed between thelever 32 and the top of the adjustable stop or sleeve 16 is a buffer orwasher 37, serving to arrest the handle or plunger, and as the stop isadjustable the amount of force exerted in printing or stamping may beregulated as desired. While I prefer to employ the lever, it is notabsolutely necessary, as a handle could be applied directly to the endof the plunger; but I prefer the lever, as it increases the power.

The operation of the device will be readily understood from aninspection of the drawings. The operator desiring to cancel or mark acheck places the latter in the'slot 3 in the main casing, moving it upagainst an adjustable stop 42, held by a set-screw #13. lle thenoperates the handle 9 of the printing-wheel until the desired characteron the dial is brought into coincidence with the index 10. Then hestrikes a sharp blow upon the end of the lever, moving the platen andcheck up against the form on the printing-wheel, as will be understood.After the wheel 5 has been adjusted with the proper characterapproximately in line with the index 10 the inking-roller 11 will serveto center it, as before described, and during the rotation of the wheelthe proper amount of ink will be applied to the printing-forms.

The printing-forms upon the wheel 5 may be removed or changed, ifdesired, or the whole wheel may be removed by withdrawing the arbor,lirst loosening the screw 6, when the head of the latter is accessiblethrough the bottom of the casing.

By making the main frame of a single casting, as shown, not only are theparts well protected, but 1 insure simplicity of construction and givethe whole device a neat and substantial appearance.

I claim as my invention-- 1. In a printing apparatus, the combinationwith a support, a freely-rotatable printingwheel mounted on an axisjournaled in the frame and having projectingprinting characters, of ayielding centering device movable radially of the printing-wheel andengaging between the type characters to center them and hold the wheelin printing position, a platen movable toward and from the wheel andmeans for operating it.
